Sanctions List Search Tool. OFAC's Sanctions List Search tool employs fuzzy logic on its name search field to look for potential matches on the Specially Designated Nationals (SDN) List and on its Non-SDN Consolidated Sanctions List.

As part of its enforcement efforts, OFAC publishes a list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific.

When full blocking sanctions in a statute or other authority are imposed on a person, that person is identified solely on OFAC's List of Specially Designated Nationals and Blocked Persons (SDN List). Any other sanctions short of full blocking that are imposed on that person are also identified on the SDN List.

How often is the Specially Designated Nationals (SDN) List updated? The SDN list is frequently updated. There is no predetermined timetable, but rather names are added or removed as necessary and appropriate.
